Multi-turn batches

Breww supports multi-turn batches, allowing you to specify how many times you need to brew (each brew being a "turn") in order to reach your required in-vessel volume.

Setting up a batch for multiple turns

When creating your planned batch, just enter the number of planned turns. Breww will then create your planned turns, splitting the planned volume evenly over each turn.

You'll be able to see the planned turns and their current status on the batch itself.

Planning which turns happen on which day

If your brew runs over more than one day, you can say which turns happen on which day. This is set in the Brewing plan card on the batch form, alongside the turn count.

• Turns -- how many times you'll use the brewing system to reach your planned volume. Pick one of the buttons, or click More... if you need a higher number.

• Brewing days -- how many days the plan spans, counted from the first brewing day to the last. Again, pick a button or click More....

• Which day -- a column for each brewing day, with a chip for each turn sitting in the day it happens on.

The summary in the top right of the card always tells you the current plan at a glance, for example "2 + 1 + 1 over 3 days".

Leaving days off in the middle of a brew

Brewing days counts the whole span of the plan, not only the days you're brewing on, so the days in between don't all have to be used. If your brewery is closed at the weekend, you can put turn 1 on the Friday and turn 2 on the Monday, and leave the Saturday and Sunday empty.

To do this, set more brewing days than you have turns. The extra columns appear as Day off, and you can drag turns in and out of them until the plan matches the way you actually work.

When a plan has days off in it, the summary counts them for you, for example "2 turns over 4 days (2 days off)".

A day off leaves your brewing system free, so it's available for another batch on the batch schedule.

Days off need at least two turns. On a one-turn batch, extra brewing days mean the brewing system stays tied up rather than being free -- see A single turn over several days below.

Moving a turn to a different day

Breww spreads the turns across the days to begin with, leaving any spare days off in the middle. To change that, drag a turn onto another day, or click the arrow on the turn to move it one day at a time.

Turns run in number order, so a turn can only move off the end of the day it's on: the last turn of a day can move forwards, and the first turn of a day can move back. Turns in the middle of a day stay where they are. When dragging, you can move a turn as many days as you like as long as every day in between is a day off, which is what lets you pull a turn across a weekend in one go.

Two things are fixed:

• Day 1 always holds a turn, because the first brewing day is the batch's planned start date. That turn can't be moved away.

• The last day always holds a turn. Moving the last turn off the final day doesn't leave an empty column at the end; the plan gets shorter instead, and the Brewing days count follows.

If you type a number into Brewing days on a batch with more than one turn, Breww holds it to 14 days, which is as long a plan as the card can usefully show.

Seeing the dates

Once you've set a Planned start date for the batch, each day is headed with its weekday and date, for example "Day 2 · Sat 22/08/2026", so you can see exactly when each turn is planned for and which days fall on a weekend. Change the start date and the dates update straight away.

If you've drawn the batch's vessel usage on the calendar further down the form, the batch takes its start date from the earliest planned vessel, and the day headings follow that instead.

A single turn over several days

A one-turn batch is a special case. The brew itself happens on the first day, but you may want the brewing system to show as in use for longer, for example while the batch is still tying up the kit.

For a single turn you can therefore set Brewing days to any number you like, and Breww will confirm what that means, for example "The brew takes place on 03/03/2026, and the brewing system stays in use for 5 days." There's nothing to drag in this case, as the one turn is always on day one.

This applies to single-turn batches only, and it's the one case where the days after the first mean the brewing system is tied up rather than free.

Seeing the planned dates on the batch

Each turn's planned date is shown in the Production turns card on the batch page, so you can check the plan without going back into the batch form. Turns that have never been given a date show as Not set.

The batch's Dates card shows the span as well. A plan with days off in it reads as, for example, "brewing over 4 days (2 brewing days)", so you can tell at a glance how much of the week the batch ties up and how many of those days you're actually brewing on.

Your brewing plan is also reflected on the batch schedule calendar; see Batch schedule (calendar) for how a multi-day brew is drawn there.

Starting and finishing turns

You can start the next turn by clicking the Start Turn X button on the batch, or from Brewing --> Start Turn X.

To end a turn and transfer it to your fermenting vessel, click Actions --> Transfer Turn X, from Brewing --> Transfer out of brewing system --> Transfer Turn X, or from Brewing --> Turn X --> Transfer out of brewing system.

You can have multiple turns in the same brewing system at the same time, so if you start the second turn whilst the first turn is still in the brewing system, Breww has you covered.

Tracking volume movements between brewing vessels

By setting up the component brewing vessels within your brewing system, for example, a Mash tun, Boil kettle etc., you can record the volume transfers between each within Breww.

To record a transfer between your brewing vessels, simply click the turn's tab within the from the batch's brewing page Turn actions --> where you can either Add volume to brewing vessel or Transfer to the next brewing vessel.

You can manage a brewing system's vessels from Production --> View --> All equipment --> View brewing system.

Enabling multi-turn on a recipe

In order to use a recipe on a multi-turn batch, Breww needs to know which stages of the recipe should be repeated per turn and which happen only once per batch.

You can do this by going to the recipe and clicking Edit recipe --> Scroll down to each stage that should be repeated per turn --> Edit --> Set Is this stage repeated per turn to Yes.

These recipe stages will then be repeated per turn on the batch's brewing page, allowing you to record readings for those stages per turn, and appear multiple times on the PDF brew sheet. Ingredients can be assigned either to the entire brew day, or an individual turn.
